I heard background noise. And woman or computer woman said he's talking to me then more just background noise then it hung up on me. I tried to call back and it goes to a computer saying "unfortunately we cannot take your call right now. " then it asks you to leave a voicemail. Not sure if human or robot call. Don't know who or what it was. Anyone know?
